This is a SetFit model that can be used for Text Classification. This SetFit model uses sentence-transformers/all-MiniLM-L6-v2 as the Sentence Transformer embedding model. A LogisticRegression instance is used for classification.

The model has been trained using an efficient few-shot learning technique that involves:

Fine-tuning a Sentence Transformer with contrastive learning.
Training a classification head with features from the fine-tuned Sentence Transformer.

Model Labels

Label	Examples
simple_chat	'What precisely is your nature?' 'What is your primary function?' 'Good morning.'
extraction	'Summarize the main benefits of this service based on the provided marketing copy.' "Can you just summarize the key findings from this research data list? I don't need all the numbers." 'Convert this list of configuration parameters into a JSON object. Keys are parameter names, values are their settings.'
reasoning	"What's the best way to pivot our struggling brick-and-mortar bookstore to survive in the digital age?" 'Develop a decision tree for purchasing a new company car, considering budget, fuel efficiency, maintenance costs, and resale value.' "What's 15% of 250?"
coding	'Refactor this C++ legacy code to use `std::unique_ptr` and `std::shared_ptr` instead of raw pointers.' 'Refactor this spaghetti PHP script to separate business logic, presentation, and data access layers.' "What's the fundamental difference between SQL and NoSQL databases, and when should I use each?"

Uses

Direct Use for Inference

First install the SetFit library:

pip install setfit

Then you can load this model and run inference.

python

from setfit import SetFitModel

# Download from the 🤗 Hub
model = SetFitModel.from_pretrained("setfit_model_id")
# Run inference
preds = model("What are the deadlines and deliverables listed in this project plan summary?")
